WebCbz-protected anilines were prepared directly from aromatic carboxylic acids, sodium azide and Cbz-Cl. [ 1] Also used in a recently reported 3-step synthesis of 1,2,4-oxadiazoles. [ … WebThe carboben- zoxy-D-glutamic acid was extracted into ethyl acetate, and the ethyl acetate solution was dried over anhydrous sodium sulfate and evapor- ated to a sirup. On treatment with ethyl acetate and petroleum ether, the sirup readily crystallized. The yield of A^-carbobenzoxy-D-glutamic acid was 6.0 g., or 85% of the theoretical.

WebThe modern era of peptide synthesis began in 1932 with the introduction by B ergmann and Z ervas of the carbobenzoxy derivative for the protection of the &-amino group of amino acids and peptides [91]. Before that time some peptides had been synthesized by methods that were laborious and very limited in their application. WebSep 15, 2010 · The synthesis of peptide involving the process of conversion of the amino acid into its N-carbobenzoxy derivative, activation of the carboxyl group, formation of peptide with the second amino acid, and deprotection via hydrogenolysis is known as Bergmann-Zervas peptide synthesis.
